、コンプレッサ１ｏの冷却負荷が大きくなる。従って、
コンプレッサ１０及びコンデンサ１１を大型化する必要

するという問題点を有していた。Problems to be Solved by the Invention However, in the configuration as described above, not only the cool storage agent 7 is cooled but also the inside of the cold storage main body 1 is cooled during the cool storage operation, so the cooling load on the compressor 1o becomes large. Therefore,
It is necessary to increase the size of the compressor 10 and the condenser 11, resulting in an increase in the size of the refrigerator unit 9 and an increase in power consumption.
又、特に冷凍保冷に使用される凝固点が一２６℃以下の
蓄冷剤７と一般に熱伝達の良い鋼管で形成される冷却管
８との間で金属腐食が発生するという問題点を有してい
た。In addition, there was a problem in that metal corrosion occurred between the cold storage agent 7, which is used for freezing and cold storage and whose freezing point is 126°C or less, and the cooling pipe 8, which is generally formed of a steel pipe with good heat transfer. .
又、保冷使用後、周囲温度や配送負荷の変動に又、冷蔵
保冷に使用される蓄冷剤は凝固点が＝１０℃１０℃程の
が採用されており、外気温が１０℃以下にもなると保冷
庫内が０℃以下となるため輸送品物が凍結するという欠
点を有していた。In addition, after using the cold storage, the cold storage agent used for cold storage has a freezing point of about 10℃, so if the outside temperature drops to 10℃ or less, the cold storage agent will be used for cold storage due to fluctuations in ambient temperature or delivery load. This had the disadvantage that the transported goods would freeze because the temperature inside the warehouse would be below 0°C.

3, a cold storage chamber body 17 consisting of a cold storage chamber 21 and a cold storage chamber 29, an insulating partition wall 26 that partitions the cooling chamber 28 and the cold storage chamber 29, and a heat storage agent 31 and a heat storage heater 32 in the cold storage chamber 29. A built-in heat storage device 30 and a condenser 37 built into the outer peripheral surface of the heat insulating wall excluding the cold storage chamber 21 of the cold storage main body 17
During cold storage operation, the cold storage agent 22 is cooled and frozen in the small volume cold storage chamber 21 partitioned by the heat insulating partition walls 26, compared to conventional cold storage which cools the entire cold storage. Since the cooling load can be significantly reduced, a wall built-in capacitor 37 with a small ineffective volume can be used, increasing the internal volume, and reducing the size of the compressor 36 to reduce power consumption. Also, cold storage agent 22
By selecting , it is possible to achieve cold storage transportation through refrigeration and freezing.

とができる。Effects of the Invention As described above, the present invention provides a cold storage compartment comprising a cold storage chamber containing a built-in cooler containing a cold storage agent, a defrosting heater, and an air supply fan, and a cold storage chamber for keeping transported items such as food cold. A main body, an insulating partition wall that partitions the cooling room and the cold storage room and is provided with ventilation holes and a ventilation fan, a heat storage device that has a built-in heat storage agent and a heat storage heater in the cold storage room, and the outside of the cold storage room side of the main body of the cold storage box. During cold storage operation, the cold storage agent is cooled and frozen in a small volume cooling chamber partitioned by an insulated partition wall, so the wall surface area is reduced compared to a conventional refrigerator that cools the entire cold storage. can be significantly reduced, so the cooling load can be reduced, the refrigerator unit can be downsized, and power consumption can be reduced. In addition, depending on the choice of cold storage agent, it is possible to achieve cold storage and frozen transportation, and it is a highly economical cold storage type cold storage that enables smooth continuous use during removal, and allows for refrigerated and cold storage transportation at low outside temperatures. We can provide storage.
